Abstract
An instrument for performing a medical procedure includes a drive shafts a holding clutch, a drive clutch, and an actuator. The holding clutch only allows advancement of the drive shaft, while the drive clutch transfers an advancement force from the actuator to the drive shaft. The dual clutch system allows a lever to be used as the actuator so that a user can generate large actuation forces manually (and optionally remotely) without significant physical effort. This capability can beneficially improve the usability and effectiveness of percutaneous surgical systems, such as those for vertebroplasty or kyphoplasty.
